This indicates a problem occurred with the URL request and can include responses such as 400 bad request, 403 Forbidden, 404 Page Not Found, 410 Removed, 429 Too Many Requests and more. A 404 'Page Not Found' is the most common, and often referred to as a broken link. View URLs that link to errors using the lower 'inlinks' tab and export them in bulk via 'Bulk Export > Response Codes > Internal > Client Error (4xx) inlinks'.","All links on a website should ideally resolve to 200 'OK' URLs. Errors such as a 404 or 410 should be updated to their correct locations, removed and redirected where appropriate. A 403 forbidden error occurs when a web server denies access to the SEO Spider's request and can often be resolved by switching the user-agent to Chrome via 'Config > User-Agent' and crawling again.","" "Page Titles: Duplicate","Opportunity","Medium","2","0.030","Pages which have duplicate page titles. It's really important to have distinct and unique page titles for every page. If every page has the same page title, then it can make it more challenging for users and the search engines to understand one page from another.","Update duplicate page titles as necessary, so each page contains a unique and descriptive title for users and search engines. If these are duplicate pages, then fix the duplicated pages by linking to a single version, and redirect or use canonicals where appropriate.","" "Security: Missing X-Content-Type-Options Header","Warning","Low","6107","49.310","URLs that are missing the 'X-Content-Type-Options' response header with a 'nosniff' value. In the absence of a MIME type, browsers may 'sniff' to guess the content type to interpret it correctly for users. However, this can be exploited by attackers who can try and load malicious code, such as JavaScript via an image they have compromised.","To minimise security issues, the X-Content-Type-Options response header should be supplied and set to 'nosniff'. This instructs browsers to rely only on the Content-Type header and block anything that does not match accurately. This also means the content-type set needs to be accurate.","" "Canonicals: Non-Indexable Canonical","Issue","High","40","0.670","Pages with a canonical URL that is non-indexable. This will include canonicals which are blocked by robots.txt, no response, redirect (3XX), client error (4XX), server error (5XX), are 'noindex' or 'canonicalised' themselves. This means the search engines are being instructed to consolidate indexing and link signals to a non-indexable page, which often leads to them ignoring the canonical, but may also lead to unpredictability in indexing and ranking. Export pages, their canonicals and status codes via 'Reports > Canonicals > Non-Indexable Canonicals'.","Ensure canonical URLs are to accurate indexable pages to avoid them being ignored by search engines, and any potential indexing or ranking unpredictability.","" "H2: Non-Sequential","Warning","Low","1","0.020","Pages with an
